12V wake-up issue may be linked to automatic sleep

Our battery charger has a “jump” mode that was able to start the Pebble. When it was profoundly dead, the jump box wouldn't work. We have gone two days now without the 12V acting up; both days, we manually put the Pebble to sleep. This is completely anecdotal, but the three times this happened to us, the Pebble put itself to sleep. Pebble support says they are working on this.
